I purchased a PRS-650 and plan to load a couple hundred books that I have currently on my Onyx Boox. I am working with Calibre software to manage and prep the files.
My questions are rather general. What file formats are better performers? Is there any value in doing format conversions to improve performance?
E.g., I've noticed on my Boox that .html and .doc formats are slow to load and I have converted those typically to .rtf or .txt files.
Also, I have some books in multiple file formats, e.g. in .epub, .mobi, and/or .pdf. Which of the above would you choose to load if you had the choice?
Any comments are appreciated. I did note
this thread had related discussion, but haven't found anything else here that compares the various file formats.
